Great video! Did you guys notice the thin blue wire that goes from a little contact to the PCB? That disconnects the electronics when the breaker is off, and lets you test the circuit without disconnecting the wires. It's also amazing how they use two solenoids on a single mechanical breaker. Surely that's half of the secret of how they could get so much functionality in one small device.
Cool, thanks for taking one apart.. I would like to know the science behind how the processor detects arc faults too. Looking forward to your next installment. Great video as usual chaps 😁
Great video 👍 , interesteing technology , my experience with certain budget brand single mod DP rcbos and bussbar combinations , has taught me that the terminals do not take any abuse , especially overtight connections . Torque screwdrivers are a must now , eventually I can see a column in test certs.
It detects the arc via listening to the low RF noise generated directly down the L & N when the arc forms it's normally quite a bit more noiser in magnitude than the general background making it quite easy to detect.
Am going to soon set up a test rig an blast some with DC - Just to see what will happen. I did help with a big test rig back in my college days. On the back out of sight or students we had switches to put faults on the test rig. Such as switching in 500 k 1 Meg 2 Meg resistors also had two way light with just a long long long run on each side L1 L2 so we could switch it in to live and neutral and also link it out just seeing good numbers don't teach you much. I have been out of it to long am reading each day on the new reg;s need to get back in to working using my brain was in dead end jobs for to long. We also had other faults to switch in and out. Took a part a socket cut one side out an soldered in a 3 ohm cut the live an stuck it in other sockets we had it on the CPC but each wired up to switch to link it out. Was for socket testing Rn L1. Some were in the junk pile I hope I still have old photos of it.
This is ovrprotection, just adding extra expense and potential problems into the system. It's not about safety it about money and profits for the manufacturers.,better to control the quality of the materials and devices that are already in production. The quality has been deterioration for a number of years.
Please stop saying MCB - That was the old BS 3871 standard. Current devices are referred to in their standard BS EN 60898 and in BS 7671 as just Circuit Breakers.

Thanks for the Premiere - really interesting to see inside this kit!

Great ,interesting thing , Now we got many of protection in one device , & it's size like a normal circuit breaker. Keep on 👍

Another great video thank you for the insight. Just amazing what Siemens have cramped into a small device
You guys are legends, regards from South Africa
Can't thank enough. Great job guys
Thanks for the video guys.
Did you find any current sensor or HF sensor inside?
It monitors HF noise and LF noise and gives command..i was keen to see the hf noise detector and current sensor within the device
Great review. Many thanks.
Excellent video. Very interesting. Thanks,
Great video lad's, JW would be proud! 👍

Great viedo like always guys

Should have used two afdd, to show both sides together.

Power it up open and take test voltages -
Don't plug it in - tear it apart
I still think it not as good - How meany faults can it clear until it fails it self
Good question - we will dig a further on this.
As close as 20000 operations
